Twitter users can already add photos and videos to posts at the one-to-many messaging platform.

Tapping on a “wavelength” icon added to the Twitter user interface will lead to a record button to speak tweets which will be posted as audio files to be clicked on.

Each voice tweet will be no longer than 140 seconds of audio. If people speak longer, what they record will be parsed into a series of tweets posted as a threaded message, according to Patterson and Bourgoin.

“People will see your voice tweet appear on their timeline alongside other tweets,” the pair said.

“There’s a lot that can be left unsaid or uninterpreted using text, so we hope voice tweeting will create a more human experience for listeners and storytellers alike.”

Twitter did not indicate when voice tweets might be available in the version of its application tailored for Android-powered mobile devices.
